Abstract: 478,066. Envelopes. PIRIE, APPLETON, & CO., Ltd., and WOLFF, H. July 13, 1936, No. 19369. [Class 146 (ii)] In a dry-sealing envelope of the kind having coatings of dry-sealing adhesive on the sealing flap and on the rear wall and a protective flap adapted normally to intervene between the coated parts to prevent premature sealing, there is furnished in the region of the mouth a two-part protective flap adapted when overlying the back wall of the envelope in an extended condition to cover the adhesive stripe on the back wall, and when folded with its related part's overlying one another to expose that adhesive stripe. As shown, the sealing flap b and back wall e have stripes of adhesive thereon which are equally spaced from the fold line of the flap. The wall e is affixed to side wings f up to a fold line g, and is extended to' form a two-part protective flap i, j divided by an intermediate fold line h. When the envelope is to be sealed, the protective flap is folded about the line h whereby the free edge of the flap is clear of the adhesive d on the back wall e. In a modification, the sealing and protective flaps are of substantially triangular form. In other examples, the back wall e is extended to a greater height, and either the terminal section j of the protective flap is folded about the line h beneath the intermediate section i to allow sealing, or folded upwardly over the section i ; in the latter case, the section i may be secured to the back wall e. Specification 458,886 is referred to.

Title: Improvements in or relating to the production of soap compositions
IPC: C11D13/02
Filed: 1939-07-08
Abstract: 533,846. Soap compositions. TENNANT, W. J. (Armour & Co.). July 8, 1939, No. 19959. [Class 91] A soap composition is prepared from a marine oil by a process which comprises the hydrolysis of a marine oil such as whale menhaden, herring and sardine oils, followed by a heating of the reaction products, the separation of the fatty acids and glycerine and then the distillation of the fatty acid mixture by the process described in Specification 533,847 to produce a special C 18  fraction substantially free from C 20  and C 22  acids and finally saponifying this C 18  fraction in the usual way to produce a soap composition. If desired the fatty acid fraction may be hydrogenated prior to saponification to remove any fish odour which may be present. The C 18  fractions of the present invention may be used alone or mixed with various other fatty acids from animal or vegetable oils. In an example sardine oil was hydrolysed by the Twitchell reagent, and the free fatty acid mixture was dried and passed through a preliminary heater before being passed into an intermediate point into a fractionating column containing a number of trays. The low boiling fraction amounting to 31 per cent of the material was withdrawn from the top of the reflux condenser and condensed. This consisted largely of the C 18  fatty acids which had an iodine value of 80 and an acid value of 216 and was saponified to produce a soap having good qualities. Specifications 533,844 and 533,852 also are referred to.

Title: Electrical switching systems
IPC: H04Q3/00
Filed: 1949-07-29
Abstract: 665,519. Switching systems. WESTERN ELECTRIC CO., Inc. July 29, 1949 [Aug. 4, 1948], No. 19993/49. Class 40 (iv). A lock-out switching arrangement for associating any one of a first group of circuits with an idle one of a second group of circuits comprises a co-ordinate field of 4-electrode gas tubes T, Fig. 1, the circuits being such that the operation of one tube precludes that of any other tube in the same row or column. Idle second circuits are represented by the closure of contacts 11, 12, and when a contact 6 is closed by a first circuit, potential is applied across the auxiliary discharge gaps of the tubes in the column corresponding to idle second circuits. The inductances 7 and resistances 8 produce sufficient potential drop to ensure striking of only one tube in a column. After a brief interval, the discharge spreads to the main gap and relay 9 operates, breaking the auxiliary discharge path of all the tubes in the row. The inductances 13 and resistances 14 ensure that if auxiliary discharge is initiated in more than one tube in a row the main discharge becomes effective in only one. The lock-out is assisted by the shunt condensers 17, 18. When the arrangement is used as in Fig. 2 for associating senders S1, S2 ... with markers M1, M2 ... , the contacts 6 and 11, 12 are controlled by relays 19, 20 individual to the senders and markers, and the interconnections are made by the relays 9. Relay 20 of a seized marker remains back until the marker has completed its function and then operates momentarily to release the associating relay 9.

Title: A process of Forming Porous Substrate Electrodes by the use of Electrophoresis
Inventor: WEININGER JOSEPH LEOPOLD
IPC: H01M4/74
Filed: 1967-05-01
Abstract: 1,181,384. Electro-phoretic deposition. GENERAL ELECTRIC CO. May 1, 1967 [May 2, 1966 (3)], No. 20075/67. Heading C7B. A Faure-type electrode is formed or repaired by electro-phoretically depositing a suitable chemically active material on a conductive substrate, having an average pore size at least 10 times greater in diameter than the average particle diameter of the active material, from a dispersion comprising by volume a major amount of a dielectric dispersing medium, e. g. water, an alcohol or a ketone, and a minor amount of finely divided particles of the active material, to which is added sufficient activator to charge the particles. The substrate may be foil, plate, sintered plaque, screen, felt, punched grid or foamed or expanded metal; foamed metal may be made by metal coating inside polystyrene foam and sintering to destroy the polystyrene. For forming a bipolar Faure-type electrode, the conductive substrate 50 is positioned between, and preferably continuously moved with respect to, two separate dispersions 90, 110 in which are positioned two separate counter electrodes 140, 150. The chemically active material in the or one dispersion may be a reducible metal compound such as a Group IIB metal hydroxide e. g. Cd(OH) 2  or Zn(OH) 2 , or in the or other dispersion an oxidizable metal compound such as Ni(OH) 2  . Alternatively, Group IIB metal oxide particles may be deposited on the substrate and subsequently converted to the corresponding hydroxide by contacting with an alkali metal hydroxide e. g. KOH. The activator, preferably less than 1% by volume of the dispersion, may be tannic acid, Cr(OH) 3 , a cellulose derivative such as Na carboxy methyl or hydroxpropyl cellulose, prolamine, or preferably yield metal ions in the dispersing medium corresponding to the metal constituent of the active material metal compound, e. g. Cd(N0 3 ) 2 , Zn(N0 3 ) 2  or Ni(N0 3 ) 2 . The dispersion may also contain electrically conductive material particles e. g. of C or carbonyl Ni suitable for codeposition with the active material. Other materials may include Ca(OH)z (for depositing Zn), MnO 2 , binders and deflocculents. The coated substrate may be subsequently pressed e.g. by rolls 250, 270, and/or dried. For forming a bi-polar Ni-Cd electrode, the substrate is maintained at a potential intermediate the potential of the counter electrodes which are each maintained at a polarity corresponding to that of the charged particles.

Title: Semiconductors
IPC: H01L21/24
Filed: 1960-06-08
Abstract: 927,873. Semi-conductor devices. WESTING- HOUSE ELECTRIC CORPORATION. June 8, 1960 [June 10, 1959], No. 20091/60. Class 37. In a process for providing a fused junction on a semi-conductor body the surface of the semiconductor body is oxidized after a molten doping member has spread over a selected area of the surface. The Specification states that a pellet of doping material, for example boron, aluminium, gallium, indium and mixtures and alloys thereof with neutral materials such as gold, silver, tin, lead or N-type material such as phosphorous, arsenic, antimony and mixtures and alloys thereof may be alloyed to a body of semi-conductor material for example silicon, germanium and stoichiometric compounds of elements of Group III of the Periodic Table for example gallium, aluminium and indium and elements of Group V for example arsenic, phosphorous and antimony. Suitable III-V compounds are gallium arsenide, gallium antimonide, and gallium phosphide. The assembly is heated in a vacuum of 10<SP>-3</SP> to 10<SP>-5</SP> mm. of mercury or a purified hydrogen, nitrogen or helium atmosphere until the doping material has dissolved some of the semi-conductor material and spread over a desired area of the surface 26. An oxidising atmosphere for example oxygen at an absolute pressure of 10 to 100 microns is introduced and the assembly heated to a rather higher temperature. An oxide film 28 (Fig. 5) forms on the exposed surface of body 22 and arrests the spread of the doping material. After the desired alloying depth is attained the assembly cools to room temperature in the oxidising atmosphere so that the activated semi-conductor material recrystallises forming the junction. Fig. 7 shows contacts 30, 32 applied to the opposite side of the junction. In a particular example indium was used as the doping material and germanium as the semi-conductor the initial temperature was 475 C. and the oxidising temperature 500 C. The Specification refers also to fusing an alloy of 5% antimony, 95% gold (by weight) to P-type germanium at a temperature in the range 500-600 C., aluminium to N-type silicon at 700-900 C., and 0.5% antimony, 99.5% gold to P-type silicon at a temperature within the range 600-900 C. Specifications 797,687 and 889,058 are referred to.

Title: A device for starting diesel engines
IPC: F02N5/02
Filed: 1950-01-02
Abstract: 677,251. Turning-gear. KLOCKNERHUMBOLDT-DEUTZ AKT.-GES. Jan. 2, 1950 [Oct. 1, 1948; Oct. 1, 1948, No. 20134/49. Class 7(v) In a device for starting two-stroke Diesel engines with piston-controlled ports, not shown, it is aranged that an electric starting motor 5, Fig. 1, tensions a spring 3 through a reduction gear 11 in the direction opposite to the normal direction of engine rotation whilst the engine is simultaneously turned backwards, the spring 3 imparting its stored energy to the engine after having been tensioned and bringing the engine within a short time to a high speed in its normal direction of rotation. A flywheel 1 is mounted on the crankshaft 2 and the spring 3 is secured at its inner end to a hub 7 surrounding the crankshaft 2 and attached to the engine housing 4; a spring housing 8, which is rotatable upon eccentrics on the hub 7, is engaged by the outer spring end. A gear ring 10, which surrounds but is spaced from the housing 8, is driven by the motor 5 through reduction gearing 11 comprising pawls operating on teeth on the exterior of the ring 10. A pawl 13, Fig. 2, on the flywheel 1 engages a notch 15 on the ring 10 whilst a second pawl 16 engages a notch 17 in the housing 8 so that in operation, the motor 5 is started and so drives the ring 10 whereupon the pawl 13 engages notch 15 and pawl 16 engages notch 17 so that the flywheel and housing 8 rotate with the ring 10 in a direction opposite to that of normal rotation and thereby tension the spring 3. When pawl 13 contacts a stop 23 it becomes disengaged from the ring 10, the spring therefore extends and drives the engine in the normal direction of rotation, both pawls being disengaged by centrifugal action upon the engine attaining operating speed. The position of stop 23 is adjustable in order to vary the tension applied to the spring and so provide for the different starting torques depending upon the  engine temperature. A fixed stop, not shown, may also be provided for starting from cold. The moveable stop is retracted by a Bowden cable, for example, if the spring has been insufficiently tensioned to start the engine so that the pawl 13 is disengaged by the fixed stop. The ends of the spring are clamped so as to prevent the setting up of reactive forces therein, and the eccentric upon which the housing 8 is mounted ensures that the outer spring end lies at a greater distance from the crankshaft axis when the spring is untensioned as compared to its tensioned position.
